In these areas, truffles which usually grow about 30 centimeters or approximately one foot are found under the ground. These are extracted either from the roots of an oak tree, an elm tress, chestnut trees and pine trees as well as in willow trees. Experts say that truffles grow symbiotic relationship with their respective environments. Then there s the Chinese Truffles. This type is considered as winter black truffle which is usually cultivated and harvested in China. This can be considered as the most widely-distributed truffle type because it grows bountifully in most areas in China. Because these are widely available, Chinese truffles are the ones that are being exported very often to the West areas and are considered an inferior-quality substitute for black truffles. However, you should be wary of the false truffles, which are not edible because of their poison. You can barely tell them apart from genuine or edible truffles, as they strongly resemble each other, not to mention that false truffles outnumber the real ones. That being said, you must be extra careful when locating and collecting edible truffles. Truffles with pungent flavor such as winter varieties can be stored in whole eggs or uncooked rice that can absorb excess flavor. If you want to freeze the truffles, you can keep them in olive oil before doing that. Make sure that the truffles are 100% covered in oil. This storage method will prevent freezer burn and capture the aroma of the truffle into the oil, hence the truffle aroma. Don t store the truffles for too long, lest they ll lose their flavor. Truffles easily diminish the strength of their flavor, so consume them soon after you purchased them. Use truffles sparingly. They re not like garlic or bell peppers that you can add to your dishes in generous amounts. Remember, these mushrooms already have strong smell and flavor, so a few slices or a little shavings will do. Preserved truffles do not have the same level of flavour as the fresh one. To enhance it, you could add truffle infused oil or paste on the recipe. According to Davidoff Caf there are tested culinary matches for each variety of truffle. Italian white truffles go great with pasta, eggs, butter, cream, chicken, walnuts, risotto and mildly bitter greens.
